The Honda turbo will hit around 60mph (real GPS), the VX 1100 will only do about 50mph. If you only want to do 50mph, then get the Honda non-turbo. The ride is much more fun than the VX. The non-turbo skis have no problems other than possible computer failure. The 10mph difference is a lot on the water, by basic math it's 20% faster.

If your mechanically savy get the Honda as it's a much more fun to ride ski. If you want reliable and don't care so much about the performance aspects and just want to cruise the n/a machine may be the way to go.
